Gene Simmons and fiancée Shannon Tweed shared an intimate lunch at Dukes West Hollywood sans kids. According to an onlooker, the two were “very affectionate with each other” and were also very friendly with their waitress. The dressed-down couple also kept things light and healthy – an egg white omelet with chicken and veggies for him, and a vegan breakfast burrito for her.
