For future reference.
What time are you guys meeting?
Don't be scared to spend money, little as it is. You'll bhave self esteem issues when ordering. It is commendable you are seeking counsel before the day.
Pick a chilled out place, drinks as you talk and laugh. Make it feel like the meal is not so important. Personally, I rarely do restuarant dates. Picnics, hikes, movies, concerts where pretense is minimal work best for me.
Halafu umeambiwa sijui chicken/chips. Priiiiisssss! Don't do that.
Try Al Yusra or Cambia on Utalii Street for Ethiopian. Damages is 700 to 1000 for a good dish. Itawatosha nyote na mbakishe. That is for lunch or dinner
