This is one of my favorite restaurants in town, and I hate to even bring it to your attention, because what if you love it like I do, and suddenly I can no longer get in for my caesar and pasta fix? Justa Pasta started out as a pasta maker, and they still supply many high-end restaurants with noodles and ravioli.
The menu is made up of salads, pastas, raviolis, and specials. If you're being careful, you can easily get a small salad and a small pasta and come away owing less than $10. The caesar is one of the city's best, garlicy and sublime. Soups are consistently fantastic. But really, this is all about the pasta—a couple types of pasta, a couple types of ravioli, a handful of sauces, all housemade. It's great. Specials, always including several lasagnas... great. Cheesecake and other sweets... great. And, the owners are really good about posting the day's specials (as well as a current menu) on the website (imagine!).
Okay, so what are the downsides, then? One, you queue up for food. Grabbing a table before you order and get your food is really frowned upon, and seriously not cool. They have a couple of bottled beers, a couple of wines by the glass, or you can select a bottle of wine while you're queued up. Otherwise, find a seat in their remodeled restaurant/lounge, enjoy a sip of whatever you're drinking, and relax. Pearl Bakery baguette comes almost immediately. The service is efficient and friendly, but you'll have to get your own water refill or fresh glass of wine. (See? Why would you want to go there, really?)
