Wow, what can I say? I'm not a vegan and I am not typically a fan of rye, pickles, or mustard -- but the Ruben sandwich was delicious!
My girlfriend and I stopped in here around dinnertime on a Saturday and found an entirely empty cafe... Friendly staff and simple but colorful decor... and as I mentioned above, the Reuben was great. Not overpowering but very tasty.
I will be back and I would highly recommend Helio Terra to anyone looking for casual dining options in downtown Cleveland.
