Fingers, Antwerp

I was in Antwerp for work today and managed to squeeze in a burger between meetings. A man's gotta eat, right? I remember going to this place a couple of years ago, when it was new, but it didn't leave a lasting impression then. Now it was perfectly placed for my lunch. The place itself looks like any franchise, but according to the website, there's just the one restaurant.

Where: Finger's Restaurant, near the central station of Antwerp
Burger: "Thumb". My first impression is that it looks real. As in different from all the plastic, right-off-the-conveyor-belt, identical looking excuses for burgers. The Thumb's got that authentic, hand-made character to it. Sinking my teeth into it, I also notice that the taste is genuine and good. Fresh greens, a nice, but small-ish patty, a great bun and to top it all off: a great sweet pink sauce, somewhere between ketchup and mayo, but with some spices to it. The burger was a real treat. Adding some more of that good fresh onion and perhaps another patty and we could be talking top marks here. Anyway, it lives up to its slogan as "Belgium's best grilled hamburgers"
Drink: A bottle of water. The shake-machine was out of order.
Side: Fries. Thin and perfectly salted. A little bit on the soft side, but the taste was great. Not to fatty, but still oily-tasting somehow. I like.
Cost: €5.95
Question:When do you open in Brussels?
