BlooiE's Roadhouse at the Rail Mall on Upper Bukit Timah Road is awesome. Seriously. I'm married to a burger fan and we've tried burgers all over the island. This burger is amazing. I don't normally like mushrooms on my burgers, but this is different. They must have cast a yummy spell on these mushrooms because I just can't get enough of them!
If you're really not in the mood for mushrooms and you refuse to take my word on it that you'll feel differently after you've tasted the Bacon Mushroom Cheese Burger (which wouldn't make sense --why would you go at all if you didn't want to take my word for it), then I suppose you can opt for the Chilli Burger. It's pretty awesome, too.
(I'm not too good at photographing food, but even so, doesn't this Bacon Mushroom Cheese Burger look yummy?)
Go try it. Even if you don't think it's THE best burger, I am certain you'll agree that it's way up there!
