I have been to Trastevere 10+ times since we stumbled upon it 3 years ago. Most times I've gone, it's been for lunch. The services is excellent and the food is even better. The bread and olive oil is the best! Their water is good, and the bus boys are usually really prompt at refilling your glass. If you order a soft drink beware- they don't offer refills. It's a bit much to pay $3.00 for a glass of soda in my opinion. Their daily specials are delicious but a bit pricier than their lunch specials if you do go during the lunch hours (11-3). They offer lunch during the week only and this does exclude holidays. The food is ready quickly it seems, just as you're enjoying your bread and olive oil. The pizza is delicious! My 5-year-old son asks for it every time. This place is very family friendly during the day. My personal favorite is the pollo e broccoli (penne pasta with chicken and broccoli in a light cream sauce) my only regret is that I can never seem to finish it all!! At the end of the meal, the waiter brings to your table a small dish of Amaretto cookies (THE BEST!) These are sooo good that I make it a rule to buy a bag of these cookies from them to take home. Parking is only $2 for 4 hours I believe. All in all, I have to say that I have never tasted pasta as delicious anywhere else as I have here. I think I might have to go to Italy to find something better? GIve Trastevere a try, you will LOVE it!
Pros: Food, Service, Food, Ambience... did I say Food?
Cons: Many tourists who happen to smoke come here, so if you want to avoid lung cancer, sit inside!
