Recipe for a perfect summer picnic:
Line up at Romados for a combo per hungry person. You will get a huge heap of chicken, hot off the charcoal grill (my "cuisse" combo had at least 2 thighs in it), peppery golden fries, salad, and a roll for about $8. Say yes to the hot sauce. Grab an interesting-looking drink from the cooler and lots of extra napkins, then walk over to Park Lafontaine, sit by the pond and gobble it all up. Even after eating your fill, you will probably have enough leftovers to make yourself a sandwich using the yummy bun.
Catch a show at Théâtre de Verdure in the evening as the sun goes down. Walk back to the métro in the twilight, eating your sandwich as you go.
I hear there are great desserts at Romados, too, but I honestly don't know how anybody could eat dessert after that big dinner. Maybe a separate trip?
