Great spot. The ambiance is totally unexpected if you see the place from the outside. Exposed brick and a sizeable bar -- it's alot like Nora's (on West Flaming) on the inside. The entrees and wine are reasonably priced with half price bottles of wine on Mondays.
As for the dishes, the penne vodka, BBQ pizza and the specials are top notch. The caprese salad is amazing -- tomatoes are always red and lush, with pine nuts and generous portions of mozz to boot. The staff is always on the ball, the bread always hot (and delicious) and even the simplest dishes have a unique, unforgettable taste to them. The chicken ceasar is a great lunch dish.
Plus there are generous portions - I always leave with a to-go box and, while I am rarely one to eat leftovers, I never leave a leftover pasta dish from Grape Street untouched.
Great place for a date. The wine flights are a great way to try something new/get a nice buzz on before dinner. I've also hosted a bridal shower in their private room and it was lovely, the service was perfect and the desserts were to die for (especially the tiramisu!).
