It depends entirely on what your site is about and what region of visitors it attracts. However, if the site isn't about anything specific and has western visitors a very general rule of thumb is that you will be able to make unique visitors per day/8, per month. As in 400/8 = $50 per month. If your site is about something specific that pays out more you can make much more than that though but at least it gives you a basic idea.
There is no hard and fast rules to estimate the exact amount get by given traffic. There are many other factors that contribute in this regard.
Aside from Adsense, you can try a partnership with any restaurants or places where people can meet and greet since it's focused on relationships.

Every click on it or reservation from your site, you get a percent share - more like an affiliate marketing.
