The coffee is mediocre and way over-priced. The service is terribly slow and occasionally wrong. Never order a sandwich from them as it can take forever and is extremely over-priced. I once ordered a sandwich from them for around $6.00. They then proceeded to forget out me and making the sandwich. Then they realized it 5 minutes later and made my sandwich (which took another 5 minutes). Then they gave it to me without an apology.
Bevande seems to survive based on the convenience factor for desperate Computer Scientists. I wish Siebel would get a better coffee shop. I prefer Espresso Royale, Paradiso or Cafe Kopi for my money.
