Here's how to visit the famous Trzesniewski cafe in Vienna. (Their slogan translates to "unpronounceably good." It's right on the money.)
Go in for a snack around 4 or 5. Select tiny open face sandwiches from the wide variety a the cafeteria style counter. Get a teeny tiny beer to wash it down with. Eric got smoked bacon and egg, mine was sweet pickle relish, a hardboiled egg and lots of paprika.
Find a table inside or stand at the high top tables outside if you've got your dog along. Set to work.
Laugh about your day. Munch. Chit chat. People watch. Relax.
Your work here is done.
