Blu Lanches
Rua 7 de setembro, 1395. this diner serves the best sandwiches in town, and try their great mayonnaise. it also gets very full of people on thursdays, fridays, saturdays before the clubs open and especially on sundays, when there are no clubs, so people would just stick around over there talking with friends by their cars and drinking some beer. it gives you a very different feel.
Top end
Restaurante Frohsinn
Rua gertrud sierich, 940. with an extensive menu and an even greater view of the city from the top of a hill, it's been many times considered the best in town. the restaurant is perched on top of a steep upward slope and offers a range of overpriced, german hybrid dishes. their goulash is made made without beer - something unheard of in germany - though you can ask for beer to be included in the source if you're prepared to pay for a bottle of beer. better german food can be found in one of the many german restaurants in pomerode. however, if you insist on eating at frohsinn, try the "marreco com repolho roxo" duck with cabbage, a traditional dish from the region. some dishes are prepared in front of you. waiters will offer a couverto starter dish, which appears to be a courtesy appetiser, however you should be aware this comes with a r$6 per person price tag specified in the menu's smallprint: the waiters will not volunteer this information. a 10% service charge is added to the bill. if you're lucky there will be a pianist playing the piano.
Moinho do Vale
Rua porto rico. right across from churrascaria ataliba, moinho do vale valley's windmill, was an ancient windmill that used to produce wheatflour and later became a restaurant. it was very damaged in the floods that hit the city in 1983, and in 2008 it was redesigned and rebuilt, becoming a nice international restaurant, and a bar with a huge deck right beside the river itajaã-aã§u. it's a nice place to make a happy hour or to go with friends. the menu comes in english, german and portuguese.

Pizzaria Don Peppone
Rua 7 de setembro, 2013. this delicious pizzeria only opens at night, but they surely have the best pizza in the city, but if you don't like too much cheese, be sure to ask for it. they also serve a superb lagasna and they have other international food dishes.
Nakirimoto Sushi Bar
Rua alemeda barã£o do rio branco. another asian restaurant, but this one only serves chinese and japanese food. if you like really thin sashimis, avoid coming here, but if you like hot dishes of the japanese cusine, this is the place for you. it has also delivery sevice. remember to ask for new glasses, without any cracks.
Miyoshi
Avenida brasil, 605. if you like asian food, specially japanese, you can find a great variety here. they have a sushi and sashimi buffet that is always fresh. there are also many hot dishes and you can also order your sushi and sashimi, if you have some kind of preference. for kids they also serve steack with french fries, and they have one of the most delicious pettit gateau's of the city. it's not the most expensive restaurant in the city, but it's becoming a splurge.
For a small city, Blumenau is quite diverse, there are Chinese, Japanese, Italian restaurants and, of course, German. There are also some fast food chains like Pizza Hut, McDonald's and Subway, all present in the city's Shopping Mall.
Except for the German food, you may have some great oportunities to have sweets in Blumenau. There are cakes for all tastes and delicious Cafés Coloniais Colonial Lunches.
In the restaurants, especially in the cheaper ones, don't expect people to speak much English. If you speak German it may be easier.
