Topolobampo or Frontera Grill?
I'm a big Bayless fan also. Maybe this will help you decide:
Topo takes reservations, although they are in demand and can be hard to gety. Frontera takes just a few; all other tables are given out as people arrive. It has been recommended that to get a table for dinner, it's best to arrive by 5:30 pm.
You can sit at the bar and order from either menu.
Topo's menu is more creative and more expensive than that of Frontera. Dinner entrees at Topo range from $25 - $45. Prices for Topo's tasting menus are not listed on-line. It also has a wonderful seafood bar.
Frontera entrees are in the $18 - $29 range.
Costs between the two restaurants are much closer at lunch if that helps. You can check out their menus on the website lited below.
