What are the best downtown Palo Alto (University Avenue) restaurants for a business lunch meeting?

I'll do three—a casual, a mid-to-high end, and a high end, focusing only on the business lunch aspects: Casual choice (and my preference): University Cafe. I like to eat and work here, although it can be a little loud over lunch. Need to demo? Wifi, free, no problem, power, too—available plugs (4 outlets, I think). Great startup vibe. For a break, watch Foursquare magic happen (here's looking at you, ). Mid-to-high range: Notoriously loud at dinner, Zibibbo is reasonable at lunch and can be nice, especially if you sit in the patio area (weather permitting). Also, close enough to the Apple Store for dessert :-> (http://www.restaurantlulu.com/Zibibbo_about.html) High end: Looking to get that SOMA feeling in Palo Alto? Tamarine is a very nice, impressive place. Always liked the vibe in the bar area more than the tables, but can't go wrong here http://www.tamarinerestaurant.com/

Lots of choices, but here are my favorites: 1. Sprout Cafe (fresh, tasty, healthy, inexpensive, fast, but a bit on the noisy side, and lines for lunch - so order in advance) http://cafesprout.com/ 2. Mediterranean Wraps (fresh, tasty, some healthy choices, nice owners, fast and efficient, inexpensive)  http://www.kanzeman.com/medwraps/ 3. Kanpai Sushi (good sushi, healthy, not as fast as the other two, inexpensive for lunch, and nice service) http://kanpaipaloalto.com/

If you are looking for a place to have an upscale business lunch, Evvia has a nice menu during the work week.  You will need a reservation though. If you are looking for something more casual, then I like Cafe Epi.  It doesn't get so loud that it is difficult to talk and menu is diverse enough to handle many different tastes.

Three suggestions : Sprout, 3 Seasons, Cafe Epi. Different styles but all of these are good options!
