I'm not sure what qualifies as "ambience" given the previous reviews, but the service and the food spoke for themselves at Thara Thai. Our waitress was phenomenally attentive and friendly; the food was delicious and as ordered. The levels of spice were just as we had requested and the food was quick to arrive and piping hot.
Thara Thai isn't trying to be fancy. It's on a back street in a largely industrial/commercial neighborhood and is housed in what seems to be a former diner or somesuch. But if you're looking for good service, good food and reasonable prices, this is your place. If you want to be wowed by hip, swanky surroundings, go elsewhere.
With two appetizers, two entrees, plus drinks, tax, and a hefty tip, our bill was about $40. Not bad at all especially since the leftovers constituted another whole meal for us. Lunch specials are available at about $6.95 a plate; the average dinner meal is about $7-9.
