Watch and see how things go. You will always be tweaking your menu. Your customers will tell you what they want and you will change your menu to reflect their tastes.
It’s been a year (March 2009 was our first day). I cannot tell you how many menus I’ve reprinted. CURRENTLY…. We are still doing 1 hot dog (2 oz all beef, same brand we started out with), smoked bratwurst (same one we started out with) and are back to the same TN style pulled pork BBQ we started out with (can finally get it out west… yeah!). We have added 2 more smoked sausages (Hot & Spicy Italian and Chicken & Apple) added another bun (for the smoked chicken sausage). Over the next two weeks, we are adding a beef meatball sandwich (using the chicken sausage bun) with 2 gravies to choose from, a very beefy thick German Style brown gravy and a Sauerbraten gravy. Both gravies are my own recipes that I have been making for our family for about 30 years. The only condiment change was we added sliced dill pickle chips (for the BBQ) and spicy brown mustard (because of the chicken sausage which is a bit sweet). And I make really fudgy triple chocolate brownies. We are down to one type of potato chip/crisp… chips/crisps just don’t do that well for us.
This is our menu until we change it… always listening to customers and trying new things that we can do on the cart. We have discovered we can do quite a bit with the cart in it’s current state but we are having to build a new bun steamer so that we can add the meatballs/gravies… requires another steam table so we will use the current bun steamer set up as a food steam table and the bun steamer will be put in a “drawer”. The meatballs sandwiches are more for events than street vending. But that may change…
I don’t think you will be getting a lot of tourists from the States. Maybe a few ex-pat’s and folks who are working who occasionally want a taste of “home”. The tourists want “real” English food… or at least what they think real English food tastes like.
