The Wife and I decided to give Which Wich a try since we were driving past and really like subs. We'll keep driving next time.
Overview (copied from their website): "Guests use red Sharpies® to mark up pre-printed menus on sandwich bags. They select a sandwich from one of 10 categories, then choose the type of bread, size, cheese, spreads, and vegetables. The sandwiches are prepared to guests' exact specifications and delivered in personalized sandwich bags. After they've enjoyed their wiches, guests are encouraged to draw on their bags with the same red Sharpies and hang their 'artwork' on the community wall."
At first, this seemed like a cool concept, but we were quickly frustrated by the fact that, having just spent time deciding what we wanted to eat and marking that info on the bags, we then had to stand at the counter while an employee inputted each of our orders -- item by item -- into the system. It would have been much faster for us to just place our order at the counter in the first place, rather than repeating the process twice.
We waited nearly five minutes for our sandwiches, even though there was no line in the place. While I understand that time and care must be put into making sandwiches, I've been spoiled by places like Jimmy Johns and Potbelly where sandwiches are made quickly and taste great.
Which brings me to the taste of the sandwiches. Meh. I've experienced better. The bread was, at best, forgettable (the Wife hated it). The meat (pastrami) was overly salty, and the sauces lackluster.
Overall, to the question of "Which Wich?" I reply, "Pretty much anyone else's!"
