I definitely agree. Helmer's rocks!!!
Awesome beer selection, and plenty of taps too. Pretty darn good Sauerbraten as well(though not as good as Mom's). Try the mixed grill for a taste of Munich.
The service can be a little slow at times, but I'm usually so hammered by the end, that I don't care.
Worth a side trip if you're in the mood for good German food, and who isn't? What is the address 11th & Washington?
