I passed by Gengenbach during my Black Forest tour.
Because I like asian food I stopped by to Thai OK. It is closed to the train station and almost right next to the post office on Leutkirchstraße.
Thai OK is a small restaurant (fast food, imbiss style) location were they have several meals a day to a special discount price. They also have a menu with some other great choices.
The people are really nice and the food was absolutely perfect. A meal is between 5€ and 6€. It was the perfect place for me as a tourist who didn t want to spend too much time on lunch, but still wanted to eat healthy. So I absolutely can recommend Thaiok. Also their website doesn't look so bad www.thaiok.de
Hope you enjoy your stay in Gengenbach - I absolutely did!
Favorite Dish: Thai noodles sweet sour :-)
This restaurant has been in the same family for at least 3 generations and, for me, is one of the best in Gengenbach. It serves local cuisine without being rustic.
By the way, it's a hotel as well. I've never stayed as my parents' house is just around the corner, but the rooms on the website look quite nice.
Favorite Dish: Definitely the deer-goulash with Spätzle (local pasta). Dark and tender and full of flavour. "Hirsch", after all, means deer, and the restaurant lives up to it's name.
If you feel like fish, try the trout from a local trout-farm. Yummy with almond butter! Or order the Neptune salad: it's a large enough for a full dinner and you get a choice of delightful bites of different fish and seafood.
The house is set beautifully on it's own up in the valley and has a nice terrace with a view of the mountains. Service is very friendly. This is a typical hiker's place, so get yourself a good walking-map and find a route that suits your mood, stamina or time-frame.
Of course you can also drive up.
Favorite Dish: Bibbeleskäs!
Bibbeleskäs is a tangy fresh white cheese similar to quark. It is flavoured with chives, dusted with paprika and served with smoked Black Forest ham, onions, farmer's bread and home-made butter. Something you won't get anywhere outside the region.
They also do delicious meat dishes, yummy omelettes and rustic, hot and cold country platters with local cold meats, sausages and cheeses.
The sizeable dishes will satisfy even the hungriest hiker.
The Turm, so called, because it is located right infront of one of the town's ancient towers, is more of a pub than a restaurant, but they do a lovely Flammenkuchen. The interior is rustic, but on week-ends you still get a very mixed crowd. Not an old-people's place, despite the dark wooden interior.
Favorite Dish: Flammenkuchen could be described as a local variety of pizza, with a very, very thin base. The classic version is topped with a type of crème fraiche, smoked Black Forest ham, onions and cheese. It's popular on both sides of the Rhine, but the German version is slightly thicker and jucier, while the French is usually lighter an crispier. Most places offer different toppings, even apple and cinnamon flambéed with calvados.
Rialto is quite a nice Italian Restaurant/ Pizzeria. Unfortunanately it's a tad unreliable. I had gorgeous food there, but I had a couple of disappointing meals as well.
Favorite Dish: their spinach and ricotta pizza is gorgeous: a light and crisp topped with juicy spinach and creamy cheese
lovely mixed salads big enough to make for a light lunch on a hot day - yummy Italian dressing
for fish-lovers: try their garlic-stuffed gilthead. My friend had it while I'd ordered pizza. I regretted my choice after trying her dish, but she wouldn't swop.
Rialto didn't pass my tomatoe-sauce test. An excellent chef can turn something as simple as Spaghetti Napoli into sheer delight, but the tomato-sauce I cook is better.
