Rendezvous Restaurant and Lounge indulges hearty appetites with a menu of hand-formed burgers, creamy pastas, and sauces made in-house at a cozy, wood-paneled setting first opened in 1927. Swirls of sharp cheddar cheese sauce saturate al dente cavatappi in the restaurant's signature mac 'n' cheese plated with a barricade of onion straws, bacon, and tomato to prevent corkscrew-shaped pasta from sneaking behind the bar and opening wine bottles. Chefs garnish 1/3-pound burger patties with a splash of homemade chili, barbecue sauce, and a slice of cheddar cheese or reimagine traditional vegetable sandwiches with gourmet enhancements such as marinated zucchini, goat cheese, caramelized onions, and fresh spinach. A chicken cobb salad balances grilled chicken breast, hard-boiled egg, and crumbles of blue cheese and bacon atop the crisp leaves of its romaine foundation. This Groupon includes all available substitutions, so diners can replace fries with yam chips or decorate sandwiches with avocado, a slice of cheese, or edible top hat.
