Therese et Dominique is one of those places where ordering the regular would be a true crime.
Although this is ‘just’ a sandwich bar, it would be a pity to go for the baguette with tuna fish you always eat. Apart from the usual stuff they have a bunch of specialties worth to be discovered. Try for instance an adapted ciccio bello, mozzarella-tomato with sweet peppers and fried aubergine slices, divine.
When the weather is nice I like to take-away my treasure and eat it sitting in the sun of the Poelaert square while doing some tourist watching, but it’s also possible to eat at the place itself, inside or in the cute garden.
Measured by the queues that might appear at the entrance it seems I’m not the only fan of the place, make sure you’re in it. Don’t worry, they work fast, you never have to wait too long.
