Beerbistro is my go-to restaurant for unpretentious, QUALITY food in a great relaxed atmosphere. I've been here twice so far and my favourite item on the menu is their steak, grilled to perfection.
Staff is extremely knowledgeable about their extensive beer selection (understatement of the year) and can help you select the best beer for your meal. Also had the trio of beer-related ice cream for dessert, which was a really fun dish and great for sharing.
The first time I came here I just stumbled upon it and it was PACKED. Fortunately another party didn't make their reservation so my friend and I got a table quickly. The second time I went, it was pretty much empty even though I had made a reservation. I would recommend booking in advance, just in case.
