Spent a couple of days there earlier this year, we're not flashy travellers so had a meal and a drink in an Irish pub which was decent to be fair.
Also went in la Trappiste which we liked although busy. Underground bar where you can try different beers, 10 euros for a tray of 5 tasters.
You have to roughly know where things are though as places like this are easily missed.
We heard about ribs n beer too but left it too late to get a table.
The brewery tour was worth it just for the free pint of zot, reasonably priced too.
I enjoyed it there and a couple of days is probably enough.
