It will open six days a week and will try to promote biodegradable packaging.
Lewis said: "We are obviously excited about the opening but we are really nervous too as we both have families to look after.
"We've worked really hard putting it together and just hope it pays off."
The cafe focuses on fresh food which is all cooked on the premises and to order, starring produce sourced locally from Felixstowe.
There will be a range of meals on offer, with breakfast options including either 10, seven, or five item plates, eight classic dishes for lunch, jacket potatoes, sandwiches, homemade cakes and a takeaway menu.
Vegan-friendly alternatives will also be available and a specials menu will be on offer on a daily basis.
Lewis says the cafe will cater for all ages, especially children, and they hope their central location will keep them "visible and visual for everyone to see".
The cafe will be open six days a week, from 7am to 5pm Tuesday to Friday and from 8am to 5pm on Saturdays and Sundays.
Good luck Lewis and Dan from Visit Felixstowe! The new Crescent Cafe Felixstowe (Crescent Road) has opened its doors for the first time this morning - with the Mayor of Felixstowe paying a visit for a delicious bacon bap and cuppa.
