The Java House is both a great spot for a light lunch or for an evening drink with friends.
I first started coming here for the occasional lunch. They have a few different sandwiches and other light fare that makes them a worthwhile destination. They've also got some decent Asian food like chow mien.
In the evening (well, all day really) you can enjoy cheap pinks and pitchers. Throughout the week they have different deals that make their good prices even better. Tuesday is a pitcher of beer and a plate of wings for about $13. Wednesday is a pitcher and nachos for $13.50 (and yes, they are decent nachos.)
They have a big patio that is often filled during the week, and always filled on Friday/Saturday. Sitting inside isn't bad either, with a variety of diner-esque booths for 2 or 4 people throughout.
