Is there a restaurant?

Yes

I think maybe a sandwich shop

Yes $10-$12 for a sandwich, descent sandwich.

We have eaten there. The pizza is pretty good, wood fired right there. Pricing is around $10-11, typical for quick service fare in tourist locations.

Yes. The "Fish Tales Cafe" offers a wide variety of grab and go lunch type foods, including gluten free options. There is also a snack bar in one of the upper areas.

There is a restaurant however we did not eat there so not sure on what they have or what it is like
