We ended up having lunch twice at Restaurant 500, since we were working nearby and it came highly…read morerecommended by locals.
The restaurant is very cute, with a rustic ambiance, two levels of seating and an outdoor patio. There's weekly specials, along with the regular menu, and you can easily sit down for lunch in under an hour.
The menu is full of classic Italian favorites; pizzas, pastas, salads, etc., with enough variety that our large group was happy about. The tuna tartare was fresh (considering we were landlocked) and my caesar salad was delicious. I also sampled the pizza and enjoyed it. The crust was on point with the right amount of toppings.
Overall, a great place to dine if you're starting to get sick of Czech food and need something different!
