I bought a few deal.com vouchers for 3 course set meal to celebrate a friend's birthday.  The voucher stated that the value of the set meal is $37, which seemed right when we tallied the offered items' prices in the menu.  However, when we were served, the portions were so much smaller than the original portions that the other tables had.  If the portions are reduced for the promotion set meal then state it so and not mislead the customer to think that the value is still $37.
There are other things that turned us off and made us not to visit the place again.
1. The actual "Green Room Cafe" is further in than the Canopy, but for lunch, we were directed to sit at Canopy.  Our food was prepared at the "Green Room Cafe" kitchen which took ages to arrive.  Other customers who came later than us and ordered from the Canopy menu got their food before us.  Our 3 course lunch took 2 hours to complete.
2. Service is terribly slow.  The bill took 15 minutes to arrive after we asked for it.
3. Water was not served till we asked for it.

We decided to grab an early dinner on Wednesday evening, and had in mind to try one of the Bishan park restaurants. We made our way to the Canopy to look at the menu. After about ten minutes of waiting outside, and seeing two staff members inside chatting away with no intention to inquire about our needs, we lost interest and started to walk away.The manager then poked his head out and halfheartedly asked me if I wanted anything. Being annoyed, I commented about the slipshod service standards, to which his face contorted into a grimace . "I thought you were just looking and going to another restaurant", was his lousy defence.   Obviously I wanted to go elsewhere, but health conscious wifey after staring at the Green Room's vegan menu also displayed at the Canopy decided this was just the thing the doctor ordered. So inspite of my better judgement, I followed her to be seated. To be fair, the food sounded interesting. I got the three course "Guest Chef" set, Wifey had the Nasi Campur. We were served the first course, a japanese ratatouille slice of seasonal vegetables immersed in jelly. Slightly more appetizing than its description, I have to admit. As I finished off the dish, I took a sip of water and realised that there was a dead ant floating listlessly in my glass. Now I know I was in for some raw cuisine but this was too much! I looked around for a waiter, but got no attention inspite of all my frantic waving.   When our mains arrived I notified the waitress of the "supplement" in my drink, to which she took one sour-faced look and without a single word of apology walked off with the drink. My main as a surprisingly comforting plate of rice, vegetables and lotus root patties drenched in a sweet-sour sauce. The flavours were right, but the textures seemed somewhat lacking. The Wifey's Nasi Campur was a sorry excuse of brown rice and limp veggies which was really bad. After another lengthy wait, we got my dessert of mochi in caramel which was actually ok, except the mochi was too hard. Finished, we sat around waiting for 20 minutes for the bill. No one came and my patience at an end I set down the amount owed on the table and walked out. Any self respecting customer will tell you I probably should not have paid for non-existent service, but the peace-loving Wifey convinced me otherwise.    As we walked to the carpark, someone came running after us and condesendingly asked us if we had forgotten to pay our bill. I told him that if the staff had been as dilligently waiting tables instead of chasing down customers for bills they might have discovered the money.  If you are in the market for a nice meal, avoid this restaurant! Which is a bit of a shame really, as the setting is rather nice and the food passably good. The management, should really get a proper service team. They have no business opening if they cannot cater to a single customer's needs, especially if that customer is the only one in the whole restaurant during an off-peak hour!  

We ventured into Green Room at the end of the compound and was immediately impressed with the ambience. It was quiet and nice. however we sat for 20 min before someone attended to us. not that we mind cause it was enjoyable sitting there. we ordered laksa and sze chuan salad. menu said big/huge bowl of salad but what came looks more like an appertize size, very small, def not main course material. i also realise one of the key ingredient - shitake mushroom is missing. i have to walk to the chef to ask if this is the case and she serve me the due serving in a small plate! Manager had attitute problem when i query why he had swiped the credit card twice. lousy experience overall. quite disappointed. setting is nice but quite a waste that everything else spoilt the dinner.
