Pre-security: DuClaw

Post-security in D/E: Market Express has gourmet sandwiches and such, Nature's Kitchen is in much the same vein. Brix & Vine Wine Bar has some interesting selections. Toward E, there's a seafood bar. By E1, there's a bar and grill, take it or leave it.

The Club (by D12) is open to all travelers for $40. As I understand, there's a pasta salad/hummus-level spread, with free booze.

If you've got *a lot* of time, hit the gym in the connector.
