It always puzzles me how some restaurants think that dervice is not really necessary. The server expected us to write down what we wanted to order, but never notified us of the fact and got slightly grumpy when she returned after what felt like 10 minutes and found out that indeed we hadn't written down anything; this may be standard for a cheap coffee shop, but when paying a good price for dinner I expect a better service than that. Subsequently our server arrived with the Sushi and told us the corresponding name, but since she took the menu we had a fun time sorting out which dish belonged to whom. The food itself was.. ok-ish. I've had (much) better Sushi, I've had worse - but I probably wouldn't return to that place next time I am in Heidelberg.
