When I lived in Indonesia from Sept 2011 – January 2012, often Lauri (The Husband) told me that he ate at this Ajino Sushi Bar in downtown area of Mannheim when he’s too lazy to cook. The price that they offered is quite a deal for the All-You-Can-Eat menu, but it really depends on what time you’re going to eat there.
Basically Ajino opens at Monday till Saturday 11:00 am – 23:00. On Sunday or holidays, they are open from 12:00 – 22:00. It is quite nice to eat here on Sunday, if you have money, since all of the other restaurants and shops would be closed at the day. Here’s the price (by March 2012) that they offered for the All-You-Can-Eat sushi:
Midday, 11:30 – 16:30 = € 12.90
Evening, 17:00 – 21:30 = € 17.90
Sunday & Holidays = € 14.90
They also have 10% Student Discount for a la carte menu, but if I wasn’t mistaken the discount doesn’t apply to the all-you-can-eat menu. The a la carte sushi dishes cost around €3-3.90, while they also have Sushi Set that starts from €13, perfect if you want to eat different kinds of sushi but thinks the all-you-can-eat would be too much for you.
