Although boyfriend Casper Smart didn't join the singer, she dined with a group of close friends – including her manager Benny Medina.
"She was in a great mood enjoying a night out on the town, " an onlooker tells PEOPLE.
Lopez was discussing "how she just finished her world tour while shooting a movie at the same time," the source adds.
The table shared every dish that was brought out to them. The group especially loved the peanut butter souffle, which they were overheard obsessing about.
After dinner, Lopez headed home while the rest of her group headed next door to SL Miami.
