I have a strange relationship with Blue Martini. It's not somewhere I usually think to go, as I usually prefer smaller and less crowded venues (like Double Helix downstairs). But despite the fact that Blue Martini is not my usual preference, I end up having a great time whenever I go.
The martinis are excellent, the food is good, and the patio has a really fun vibe.
The only downside is that they don't take reservations for dining. You can buy a table in the club area, but you can't reserve a patio spot for dinner. It's usually not a problem though, as long as someone in the group gets there early to scope out a table.
