This place Cleveland landmark for a reason. Awesome draft beer selection, $5 flat price for a hot dog/ vegan dog with unlimited toppings, and tater tots/ fries are also flat price w/ unlimited dips. PLUS events such as polka happy hour (what?? yes.), science talks, live music, and more. There's also a downstairs area, called the Underdog.
They get super busy especially during happy hour, so expect to wait a little while to place your order & get food. Also, on weekend nights (and sometimes on Thursdays) they may have live music and charge a cover, usually after 9pm. If you're in before that it's fine.
