So to make a long story short me (23M) and this girl (20F) are what I consider friends and she said she really wanted to go to this restaurant that just opened. I managed to get a res for tommorow night but just for 2, since it was initally a plan of 4 people but there was no availability. She brought up the idea of just us 2 as a date, but said it in a playful manner. (She brought it up a few times afterwards)

I do not know wether to take it seriously, but I actually made that reservation just in case. Should I go with a plan or text her to remind her? I am a bit confused what to do since I don’t really like her like that but she is attractive so I wouldn’t mind. Should I do a flirtatious or soft friendlly approach?
