Tilli's makes for a nice night out with the girls--plenty of diet friendly menu items and local eye candy (of course, there are many items on the menu NOT diet friendly too!). The food to price ratio is about average in this neighborhood; you can spend as little ast $10, as much as $30 or $40 depending on your choices.
My favorite parts of the Tilli's dining experience: roaring fireplace open on both sides to the dining and bar areas, and the short, Italian country-style wine glasses (no stems). The patio is a great place to be on warm evenings, especially because traffic noise doesn't seem to overpower the conversation.
Bathroom is nice and has always been clean when I've needed to use it. Service is also better than average.
Tilli's is an excellent choice when you want to go out for a semi-nice meal, but just can't get anyone to make up their minds on where to eat.
