Ladies and Gentlemen:

In connection with the existing Registration Statement on Form S-3 (File No. 333-237664) (the “Registration Statement”) of Dave & Buster’s Entertainment, Inc., a Delaware corporation (the “Company”), filed on April 14, 2020 with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Act”), and the rules and regulations thereunder (the “Rules”), you have asked us to furnish our opinion as to the legality of 1,436,781 shares (the “Shares”) of common stock of the Company, par value $0.01 per share (the “Common Stock”), which are registered under the Registration Statement and which are subject to sale pursuant to the Underwriting Agreement (the “Underwriting Agreement”), dated as of May 4, 2020, by and among the Company, and Jefferies LLC, as the underwriter.

In connection with the furnishing of this opinion, we have examined original, or copies certified or otherwise identified to our satisfaction, of the following documents:

In addition, we have examined (i) such corporate records of the Company that we have considered appropriate, including a copy of the certificate of incorporation, as amended, and by-laws, as amended, of the Company certified by the Company as in effect on the date of this letter, and copies of resolutions of the board of directors of the Company relating to the issuance of the shares of Common Stock, and (ii) such other certificates, agreements and documents that we deemed relevant and necessary as a basis for the opinions expressed below. We have also relied upon the factual matters contained in the representations and warranties of the Company made in the documents reviewed by us and upon certificates of public officials and the officers of the Company. 

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of all such latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete. 

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that the Shares have been duly authorized by all necessary corporate action on the part of the Company and, when issued, delivered and paid for as contemplated in the Registration Statement and in accordance with the terms of the Underwriting Agreement, the Shares will be validly issued, fully paid and non-assessable.

The opinion expressed above is limited to the Delaware General Corporation Law. Our opinion is rendered only with respect to the laws, and the rules, regulations and orders under those laws, that are currently in effect.

We hereby consent to the use of this opinion as an exhibit to the Company’s Current Report on Form 8-K filed by the Company with the Commission on the date hereof, and to the use of our name under the heading “Legal Matters” contained in the base prospectus included in the Registration Statement and in the Final Prospectus. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required by the Act or the Rules.
