We got to Opera pretty late (10:45 p.m.), so I was happy that they're open late. They recommend making reservations, as it's a popular place in the theater district. The decor is pretty cool and artsy-unusual, and the service was friendly and prompt.
I also love that they have a separate vegan menu, however small it may be, and however confusing (it's not separated into traditional groupings of appetizer-entree-dessert, so make sure to ask what's what).
Now onto the food. The morel mushroom wontons were pretty good but nothing spectacular. Morels are delicate, so I wasn't sure that deep frying them in batter was the best cooking treatment. The portion size was kind of small considering the price ($9).
My Mapo tofu was also decent, but nothing special. The portion size was much larger, even though the price was only $8, so I'm not sure how they set prices. The flavors were a strange mix of sweet and spicy, but I found the dish became boring after ten or fifteen bites.
There were two other vegans in my group and one of them was greatly disappointed by her "vegetable rice noodle stir fry" which she found to be overly sweet with low quality noodles. I tried her dish and concurred---it was almost sugary, rather than savory. Finally, the last vegan in the group enjoyed her "spring vegetable muushu."
So while I must give the restaurant kudos for having a vegan menu, and having hip decor and nice service, I was not impressed by the food. Quite honestly, I probably won't go back here unless I'm desperate. It just doesn't merit a second visit.
