If you're in the Coachella or Palm Springs area and you are a fan of massive tasty sandwiches, you have to try TKB.
It can get crowded during the lunch rush, so you might consider ordering online ahead of time.
The sandwiches are expensive, but they are much bigger than traditional deli sandwiches.
If you have a gluten sensitivity, you might look elsewhere. I didn't see an option for gluten free bread.
