This is a mediocre Thai joint, not unlike most of the other Thai places in New Haven. The menu here is nearly identical to that of Rice Pot on State Street (they must have the same owners), though I found the service and ambience at Rice Pot to be better than that of Thai Taste.
The place looks like it might be swanky but it is, in fact, something akin to your best friend's wood-paneled 1970s rec-room. There was duct tape on the wall near where I sat. As such, I don't think this is a great date spot.
The service wasn't terribly friendly but at least it was prompt.
I had a "hot basil" stir-fry with tofu ($7) and brown rice ($1). I asked them to leave out the fish sauce, which isn't disclosed on the menu (see the paragraph below for more info). It was a small portion of stir-fry with exactly two small cubes of tofu. Rice Pot was similarly stingy when it came to tofu quantity; what's the deal with that? While I appreciated the brown rice option, I found the stir-fry itself to be bland and overly simple. Thai food is known for robust flavors but the food here felt watered-down and bastardized.
As with pretty much every other Thai restaurant in the US, make sure to ask about fish sauce, oyster sauce and shrimp paste if you're vegan or vegetarian. Most of the dishes at Thai Taste, including those labeled "vegetarian" contain either fish or oyster sauce by default, but can typically be modified; conversely, all of the curries contain shrimp paste pre-mixed, and cannot be modified to be fully vegan or vegetarian.
I'd skip Thai Taste, if I were you. The place across the street, Thai Pan Asian, has better service and better food; go there instead.
