Ok- so - when in Mainz I wanted to get a "wine-based" restaurant in Germany - I googled wine…read moretasting restaurants -and this restaurant showed up. Well I went and it failed in almost every way. Where do I start.... Walked in and the seats were all booked out. I have NO problem with this.... But they led us to one table that was for diners who did not have reservations. Ok - it was inside, it was hot, but shame on me for not pre-booking.... That is on me! So - thinking we were going to get some good wine advice- after all - it was listed as a wine tasting place.. we picked some food items - and asked for advice... well - no real advice at all...actually nothing. Ordered some food. It came out with the wine that was arbitrarily selected. Ate it, drank it. Whatever.... Then the other server came over.... Asked what we else wee would like.... She pretty much said - I don't drink so I don't know - don't ask me. On this I am thinking - why the hell should she ever serve in a Weinstube. She took an order - and what do you know - NOTHING! Nothing ever came - nothing ever said.... Nothing. So crappy wine advice.... The second server never showed up and clearly did not give a damn about service. After 30 minutes of waiting for the dessert we ordered not showing- we threw in the towel. SO - WOULD NOT RECOMMEND
