You won't find a better gateway beer than the belgian blonde ale. Most people are familiar with the likes of Leffe and Hoegarden. In fact the style itself came about as a means of appealing to a much wider pilsner drinking audience, so in terms of Belgian beers its very approachable for people new to craft beer. Its still a Belgian strong ale, but its maltier and sweeter than a triple, with a much lower alcohol content. The 'sweetness' should be a pilsner malt character rather than a residual sugar sweetness, not much hop aroma or flavor and above everything else the beer should be dry and drinkable.
