Cali Sandwich is probably the best bang-for-your-buck that you'll find anywhere near Downtown. The appearance and cleanliness may leave a little to be desired, but I've been eating there for years and have never found so much as a hair in my food. $2 grilled pork sandwiches are excellent, but everything they have is an great value for what you get: lots of healthy food for a low price. Their vermicelli bowls, hot french coffees, and smoothies are also outstanding. Vietnamese food in general is pretty healthy stuff, so even if you eat a lot, you are not going to pack on the pounds (my co-workers and I haven't). The service is debatable at first, but if you become a regular customer and they recognize you when you come in, the service is top-notch. They value repeat business. Also, if you are at all worried about the looks of the place, or the cramped size, the owner confirmed that they are going to be moving to a bigger space in the same shopping center which, as others have mentioned, is nearly done being remodeled. Hopefully this will improve the long lines and service speed. Overall though, if you are looking for cheap, fast, and healthy, Cali is a great way to go. $5 will get you a bowl of rice, a 8-inch sandwich, and a coffee (or smoothie) and you'll be stuffed. Just make sure to take the jalapeno out of your sandwich if you don't like things really spicy!
Pros: Cheap, healthy, tasty, and they value repeat business
Cons: There's no such thing as ""too cheap!"" Long lines at lunch.
