Good Italian, not too expensive, near Jean-Talon market
I'd suggest Pizzeria Napoletana (Dante/de Gaspé), Bottega (St-Zotique/St-Dominique) or even Vinizza (Jean-Talon/Casgrain): all three have pizzas and pasta ranging from $12 to $25, I'd say. Via Roma is also a good one, but a bit more expensive.
