Just getting back from a trip to Oslo - will give a rundown of meals. First off - everything is expensive, so you'll need to get over finding a cheap meal - its hardly possible.
First day - Lunch at Cafe at Grand Cafe - everywhere you go for lunch buffets with open faced sandwiches are the norm. They are nothing that special - and all pretty average. Just know that when its a buffet - its not all you can eat - you pay for what you take. So, with this being a ridiculously expensive city - probably not the best idea that my fiance decided to try several things to taste.
Dinner at A Touch of France - I went with very low expectations bc I was just in Paris and also bc the name is so bad. Great meal- probably made better bc the service was so great - a charming man with a grey ponytail - ask for him when you go. we had a chevre salad - delicious, escargots with chantarelles - very good. Out of the entrees - the steak was average, the veal livers was good, and the duck confit was terrific. Their "calorie cart" a dessert cart was great and full of unique sweets.
Second day - lunch at Engelbert Cafe - the atmosphere is just perfect and the lunch again a openfaced sandwich buffet. Its worth it for the atmosphere.
Dinner - Lofofen was closed so we went to their other restaurant Havsmat - this was a great meal. we all got their prix fix deal and every bite was delectible. Great service and atmosphere.
Third day - quick grab and go lunch - for $60 eeks! Dinner - Grand Cafe - so disappointing - wonderful atmosphere - but the only way to describe the food is BAD.
Hope this helps anyone going to Oslo!
